MAR Consulting was contracted to perform a functional safety assessment (FSA) stage 3 of overpressure protection functions in an offshore platform in the Norwegian Continental Shelf (NCS). The main objective of an FSA is to demonstrate compliance with IEC 61511 and 61508 functional safety standards, NOROG 070, and Petroleum Safety Authority (PSA) regulations through an independent assessment of the development process. Hence, the FSA process is a fundamental tool to ensure that the Safety Instrumented System (SIS) fulfills its requirements as an active barrier to reduce risk to acceptable levels. The FSA team shall have some degree of independence to […]
MAR Consulting performed an investigation on the safety systems of an offshore platform in the UK sector. Focus was on the Emergency Shutdown (ESD) and Anclilliary systems such as Safety Instrumented Systems (SIS). A list of findings and deviations of the current design and design documentation was presented to the client. The outcome will be used by the client to improve the safety of the design and meet requirements from UK regulators.
MAR Consulting supported the development of a Reliability, Availability, and Maintainability (RAM) study for a new field subsea tie-back in the Norwegian Continental Shelf (NCS). The objective of the study was to provide the production efficiency (PE) estimates for the subsea field value chain in accordance with a revised base case and a high-level assessment for other three cases with different number of wells. In addition, a sensitivity analysis was performed for increased mobilization times due to no spare parts for the subsea production system (SPS), and subsea umbilical riser flowline (SURF).
MAR Consulting facilitated a Design Review for the HVAC systems in a Floating Production, Storage and Offloading (FPSO) vessel, as part of lifetime extension modifications. The workshop was performed online with discipline experts from Engineering Contractors and Operator. The workshop was structured as a qualitative analysis following a list of guidewords to make use of the multidisciplinary experience and knowledge of the participants. The objectives of the workshop were to: Identify gaps towards Authorities rules & regulations and Client / project requirements; Review the current design with regards to safety, operability, and maintainability, i.e., areas where it may represent a […]
MAR Consulting has entered a yearly agreement to provide support on-demand services to a gas operator in Norway. The services are related to the evaluation of production performance and regularity based on field modifications and implications to the gas network.
MAR Consulting supported the development of an availability study of a new concept for low voltage (LV) power supply to auxiliary systems in offshore wind substations. The concept proposed includes less redundancy. Therefore, it is essential to understand how it may impact the availability of the LV wind power substation. The substation’s main objective is to transmit offshore wind power to the onshore grid. For this purpose, auxiliary systems are essential to maintain the substation operationally capable. Failure of power to auxiliary systems such as cooling pumps, etc results in the inability to transmit power to shore. It was concluded […]
MAR Consulting facilitated a wind power system design review for an offshore substation platform. The platform receives power generated from offshore wind turbines (North Sea) and transmits the power to shore. This is a follow-up to the internal design review performed with the engineering company. In this review, the operator also participated – both the project team and operational organization. The main objective of the system design review of the wind power platform was to ensure that the system design is in accordance with the Authorities’ rules & regulations and the Client’s requirements. We focused on process safety, operation, maintenance, […]
MAR Consulting AS updated a Failure Modes, Effect, Criticality and Diagnostics Analysis (FMECA / FMEDA) of the hydraulic control and safety systems of a major drilling contractor’s subsea drilling BOP. MAR Consulting had performed the previous original FMECA / FMEDA based on API S53 4th Edition and the US Code of Federal Regulations (CFR). The new rig contract requires compliance with API S53 5th Edition and therefore warranted the update. And it is outside the Gulf of Mexico where the US CFRs are not applicable. This work is part of the partnership to develop a BOP digital twin and failure […]
MAR Consulting will support an Engineering, Procurement, and Construction (EPC) contractor for a Liquified Natural Gas (LNG) production site in Germany. The position is functional safety specialist engineer. The plant will receive bio-methane of controlled origin directly from the gas distribution network. Downstream, the plant will process the gas to supply heavy-duty transport across the country. The project is currently in its initial phase. Hence, MAR Consulting will provide expert knowledge in all phases of the LNG project. Until final commissioning and delivery to the operator. Work tasks are mainly preparation of main SIL related documentation. Such as SRS, SIL […]
MAR Consulting facilitated an online internal system design review for an electrical offshore platform. The platform receives power generated from offshore wind turbines (North Sea) and transmits the power to shore. This is a follow-up to the E-HAZOP performed: EHAZOP offshore wind power transmission platform · MAR Consulting. The main objective of the system design review of the wind power platform was to ensure that the system design is in accordance with the Authorities’ rules & regulations and the Client’s requirements. We focused on process safety, operation, maintenance, and interfaces to ensure the design of optimal solutions and that integrity […]
